My gut reaction would be to split the difference.
I'd use as-is, but increase DC by +2 is the spell isn't on your class list and +4 if the spell is a different type of magic (arcane/divine; yes, I realize raw 5E doesn't focus so much on arcane/divine).
I'd also probably use INT (religion) or INT (Nature) depending on the class list.
A smart wizard with a religion background is going to be fairly decent at casting from cleric scrolls and the same for a magic domain/theme cleric for wizard spells. Outside of that, they both know it can be done, but it is almost always better to just get the right guy on it.
A pure fighter is always going to be looking at a +4 DC and probably a very poor roll. But it is not remotely disallowed.
Then you create scenarios that produce conflict over how much risk to take.
Maybe a wizard carries a few emergency L1 spells knowing the odds are 50/50.
Or maybe the party knows that a scroll of Lightning Bolt is going to be key to some challenge, but only the fighter will be able to get in the right place at the right time. The party has a couple days to figue out how to stack the odds in the fighter's favor.
